The Jellyfish Nebula is a supernova remnant in Gemini. This nebula has a lot of filamentary detail along the "shell." It is positioned close to another dimmer nebula, SH2-249, seen towards the left of this image, with a faint bridge between them. This is in the HOO palette.
This image was taken months ago, which I had planned to process but subsequently forgot about until I found it on my ssd. This was only about 5 hours of data and I am very happy with how this came out!
Subs:
300s narrowband: 30xHa, 30xOIII
30s RGB: 15xR, 15xG, 15xB
Processed in PixInsight, combined rgb and narrowband data (HOO), then spcc, blurx, noisex, starx on both images, then use generalized hyperbolic stretch on nb image, re-extracted color channels from nb, stretched oiii seperately, recombined, several curves adjustments, darkstructure enhance script, stretched rgb stars then used imageblend to recombine
Equipment: Sky-Watcher Star Adventurer GTi, William Optics RedCat 51 WIFD, QHY miniCAM8 Mono, William Optics Uniguide 120, ZWO ASI174MM Mini, QHY miniCAM8 Ha filter, OIII, R, G, B filters
